BioCluster

BioCluster is a peer-to-peer clustering platform
for Asterisk, the open source PBX, which allows
Asterisk to be used as a full carrier-grade
telephony solution. It is meant to be installed on
several machines together with Asterisk, turning
them into a VoIP cluster. While the BioCluster
peer-to-peer protocol was initially designed to
cater to Asterisk-based clustering solutions, the
BioCluster framework is capable of being extended
to support various forms of normally unclustered
devices or software packages.
